WebThe dynamic_bitsetclass represents a set of bits. provides accesses to the value of individual bits via an operator[]and provides all of the bitwise operators that one can apply to builtin integers, such as operator&and operator<<. The number of bits in the set is specified at runtime via a parameter to the constructor of the dynamic_bitset. Webstd::bitset:: to_string. Converts the contents of the bitset to a string. Uses zero to represent bits with value of false and one to represent bits with value of true . The resulting string contains N characters with the first character corresponds to the last ( N-1 th) bit and the last character corresponding to the first bit.
